The 44-year-old, who hasn’t aged since she booty-shook her way into the limelight 15 years ago, gave her fans a peek of her sizzling judge’s outfit with the caption #idolfashion.

The talent show is currently in its season 13 audition stage, and the mother-of-two looks set to be a main attraction.

Lopez, who is dating 26-year-old dancer Casper Smart, recently shared her fashion tips with a lucky young winner of "My Fabulous Quince" contest- a competition giving you a chance to let your favourite star style you and your birthday party.

Speaking about her experience styling young winner Alyssa Llinares, J.Lo revealed:

‘Alyssa knew exactly what she wanted, which always helps. It made the whole process easier. She had a real vision for herself.’

The lucky youngster settled on not one, but two custom dresses by designer Johnathan Kayne.

‘This is so up my alley. I'm always the Barbie doll, and they're always dressing me up and doing my hair and makeup, but I love dressing people up, too. This was a pleasure for me! This was the easiest thing they could have asked me to do,’ the I’m Real star revealed.

Who wouldn’t want to be styled by J.Lo!
